No specific information

6. Minor release updates[edit | edit source]

STMicroelectronics regularly delivers corrections through github® components which are U-Boot, OP-TEE, TF-A , linux kernel, external-dt .


The corrections can be incorporated into theSTM32MPU Developer Package or Distribution Package (see below).

Two possibilities exist to update a Distribution Package:

  • Update your existing Distribution Package:
Switch your Distribution Package to # github® mode .
  1. Use the devtool modify <recipe name> command to set up an environment. It fetches and unpacks the source code.
  2. In the extracted source code, use a git command such as git checkout -b WORK <github® TAG> to point to a new revision of the component.
More rarely, STMicroelectronics also delivers fixes on layers through github®. These changes can be integrated (via git commands: git checkout -b WORK <github® commit SHA1>) into the local STM32MPU Distribution Package environment. See below the github® links of the quoted layers :
  • Get a new Distribution Package:
Refer to Installing_the_OpenSTLinux_distribution page for installing instructions, and use the repo command given for the minor version below, if it exists.
